The purpose of this study was to reduce ghost artifacts due to phase correction error and to reduce slice leakage artifacts in dual-band EPI, using pre-scans with a half-sized phase encoding (PE) blips technique. A phantom and in vivo rat brains were scanned using a custom single-shot dual-band 2D-EPI sequence with blipped-controlled aliasing (CAIPI) on a 7T animal scanner. The pre-scans with half-sized PE blips were useful to achieve accurate phase correction in EPI, and to estimate coil sensitivity profiles for each slice, resulting in the reduction of slice leakage artifacts in dual-band EPI with CAIPI.
